Rewrite in improper fraction form :
[tex](\frac{6}{3} +\frac{1}{3}) -\frac{1}{2} \div \frac{3}{4} + (\frac{9}{3} +\frac{2}{3})[/tex]
[tex]\frac{7}{3} - \frac{1}{2} \div \frac{3}{4} + \frac{11}{3}[/tex]

Answers
The time taken to cover a distance of 814 miles for Caynon's home will be 22 hours.
What is speed?Speed is defined as the ratio of the time distance travelled by the body to the time taken by the body to cover the distance.
Given that:-
The distance to your brother's house is 481 miles, and the distance to the Grand Canyon is 814 miles. If it took 13 hours to drive to your brother's house, how long would you estimate the drive to the Grand Canyon to take?The time will be calculated as:-
First, we will calculate the speed to cover the distance of Brother's house:-
Speed = Distance / Time
Speed = 481 / 13 = 37 miles per hour.
Now the time to cover a distance of 814 miles will be calculated as:-
Time = Distance / Speed
Time = 814 / 37
Time = 22 hours
Therefore the time taken to cover a distance of 814 miles for Caynon's home will be 22 hours.

what is the solution to the trigonometric inequality 2sin(x)+3>sin ^2(x) over the interval
Answers
The intervals that satisfy the given trigonometric Inequality are; 0 ≤ x < 3π/2 and 3π/2 < x ≤ 2π
How to solve trigonometric inequality?We are given the trigonometric Inequality;
2 sin(x) + 3 > sin²(x)
Rearranging gives us;
sin²(x) - 2 sin(x) - 3 < 0
Factorizing this gives us;
(sin(x) - 3)(sin(x) + 1) < 0
Thus;
sin(x) - 3 = 0 or sin(x) + 1 = 0
sin(x) = 3 or sin(x) = -1
sin(x) = 3 is not possible because sin(x) ≤ 1.
Thus, we will work with;
sin(x) = -1 for the interval 0 ≤ x ≤ 2π radians.
Then, x = sin⁻¹(-1)
x = 3π/2.
Now, if we split up the solution domain into two intervals, we have;
from 0 ≤ x < 3π/2, at x = 0. Then;
sin²(0) - 2 sin(0) - 3
= 0² - 0 - 3
= -3 < 0
Thus, the interval 0 ≤ x < 3π/2 is true.
From 3π/2 < x ≤ 2π, take x = 2π. Then;
sin²(2π) - 2 sin(2π) - 3
= 0² - 0 - 3
= -3 < 0
Thus, the interval 3π/2 < x ≤ 2π is also true.

If 30% of a number is 78 and 65% of the same number is 169, find 95% of that
number.
Answers
Answer:
let say the number is x, then 30x÷100=78, x=260...from this we can calculate 95 percent of 260 which is equal to 247
The 95 percentage of the number is A = 247
What is Percentage?A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %
The difference between an exact value and an approximation to it is the approximation error in a data value. Either an absolute error or a relative error might be used to describe this error.
Percentage change is the difference between the measured value and the true value , as a percentage of the true value
Percentage change =( (| Measured Value - True Value |) / True Value ) x 100
Given data ,
Let the number be represented as n
Now , We can set up two equations based on the given information
30 percentage of the number is 78 ,
So , 0.3 ( n ) = 78
0.65 ( n ) = 169
Solving for n in the first equation, we get:
n = 260
Substituting n = 260 into the second equation, we can check that it is true:
0.65(260) = 169
Now, we can find 95% of the number by multiplying it by 0.95
0.95 x 260 = 247
Hence , 95% of the number is 247

From the information,we get:

One stack is given,that is = 4 3/4 inches.
To Find:
The height of the other.Solution:
Let us assume that the other height of the book be x.
Then the equation will be:
[tex] 4\cfrac{3}{4} + x = 7\cfrac{1}{2} [/tex]
Solve for x to get the other book's height.Convert the mixed fractions to fractions:
[tex] \implies \: \cfrac{19}{4 } + x = \cfrac{15}{2} [/tex]
Subtract 19/4 from both sides:
[tex] \implies \: x + \cfrac{19}{4} - \cfrac{19}{4} = \cfrac{15}{2} - \cfrac{19}{4} [/tex]
[tex] \implies \: x = \cfrac{11}{4} =\boxed{ 2 \cfrac{3}{4} \rm \: inches}[/tex]
Hence, we can conclude that:

Step-by-step explanation:
The equation of a circle is; (x+7)²+(y-6)² = 50
What is circle?A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre.
The points on the circle are L(-2, 11) and centre is N(-7, 6)
Find the radius,
D = √(-7+2)²+(6-11))²
D = √25+25
D = √50
We know that, the equation of a circle is given by,
( x − a )² + ( y − b )² = r² , where ( a , b ) represents the centre of the circle,
Here, centre is N(-7, 6)
Therefore, the equation of a circle is;
(x+7)²+(y-6)² = 50
